At the heart of the ARM 7” FMIC is the intercooler core with our all new ULTRA-Dense fin packs. With 18 fins per inch, the ARM 7” FMIC is at the top of its class for core density and cooling performance. Not surprisingly, it can cool the charged air of your 535i as efficiently as intercoolers larger than it, without the pressure loss associated with those larger intercooler upgrades.
The ARM 7” FMIC measures 20 x 7 x 5.75 inches for a total of 805 cubic inches, almost DOUBLE the size of the OEM 535i intercooler and 180 cu in larger than our 5” FMIC. Combined with our Ultra-Dense fin packs, not only are you getting a substantially larger intercooler, but also one that utilizes its size efficiently for maximum cooling performance.
While testing the 7" FMIC for it's ability to cool the charged air, we found that IAT's increased only three degrees during a 3rd gear datalog. Considering our baseline test with the OEM intercooler resulted in a performance-robbing IAT increase of sixty degrees, the ARM 7" FMIC has 95% better cooling performance than the OEM 535i intercooler.
When testing the 7" FMIC on a Stage 2+ N54 335i we found it made an average of 10whp/10wtq over our 5" FMIC upgrade and 35whp/38wtq over the OEM intercooler!
FITMENT: The OEM 7” FMIC does NOT require removal of the front bumper, but will require some trimming of the plastic shroud behind the bumper. FITMENT GUIDE
